Smartphone Attachment Can Test For HIV In 15 Minutes
stephendavion writes A team of researchers from Columbia University have developed a device that can be plugged into a smartphone and used to quickly test for HIV and syphilis. The mobile device tests for three infectious disease markers in just 15 minutes by using a finger-prick of blood, and draws all the power it needs from the smartphone, Science Daily reports. The accessory costs an estimated $34 to make and is capable of replicating tests done in a laboratory using equipment that costs many thousands of dollars.
Imagine if you can prick the finger of a hooker in a Pattaya bar while you're drinking, "just as a joke!", and figure out whether you need to strap on a condom or not. Wonderful invention for all the people who need immediate HIV tests for their partners! Yay for sex tourism!
Until it goes wrong and doesn't work. This type of thing is a litigation nightmare. Looks like vaporware to me, and the actual legitimate applications seem few.
Who are they selling too? I'm not into the club scene but I can't really see many people looking for a one night stand using this. I can see doctors using this but at even 250 resale value they won't sell enough units to just doctors to make them capitalist idols.
Here is a link to the original article cited by the Times that contains more detail.

The accessory costs an estimated $34 to make
which means it will cost $34,000
"Pricking yourself with something that an infected person used is a sure-fire way to get an infection.
It's as if you don't even know how diabetic test strips, and other test strips like this one, work, or even that lancets of all kinds are disposable.
If you RTFA and click through to the Science Daily article, you'd read this:

That is fucking spectacular.
Shut the fuck up.

The device has replacable cassettes that contain the reagents for the testing. To develop a device like this only to have it capable of spreading infection would be an incredibly stupid oversight.
Too bad HIV has a window period of three weeks to three months.

Because the medical researchers who developed the AIDS testing smart phone attachment didn't think of that, and you did.

Is the tool able to determine by itself locally the outcome of the data, or does it send the data for analysis remotely? If it's the latter, there's a big privacy concern here.

Ok, tell the truth now: From just reading the headline, how many of you had interesting/disturbing/funny/twisted mental images of how one would test HIV with a smart phone?

And, if you hook the same chemical reactions and transducer technology to a smartphone you can reproduce the same information generated from those chemical reactions and transducers hooked to ... wait for it... a computer.
Smart phones are much more common than desktop computers in poorer countries. So yes, making a smaller, cheaper, reliable device for a smart phone is a big deal.
It isn't like you can use the same smartphone dongle over and over again for very little cost.
It isn't? Sure seems that's what they're doing, but I'd love to hear your logic as to why that's not what's happening.

"run assays on disposable plastic cassettes with pre-loaded reagents"
There is some material cost to actually *using* the thing. It's unclear what that cost is, but there are disposable materials involved.

Hey, no worries, this is Slashdot!
Give him a couple more years sitting on his couch-bed in his mother's basement drinking Mountain Dew and eating chips while playing video games and troling Slashdot.
He WILL know all about lancets! Or be dead. One or the other.
This is perfect for iPhone users!
It's using the smartphone to display the results so they don't have to include a screen on the device, and it's using the power from the phone instead of having its own batteries. It's not exactly the smartphone doing any of the testing. It's just another case of normal computing done on a smaller computer somehow being news. They could easily add a screen and a battery but that would raise the cost of the device and not force users to have much more expensive smartphones. Sometimes it's far better to have a standalone device.
Are you retarded? If you answer no you should seriously get yourself clinically tested.

These kinds of strips are far cheaper, easy to use, don't require power, don't require a smartphone, etc.
Which is why all diabetics have to go to the doctors office several times a day to get their glucose tested.

FTFA (referenced by wed128), it uses some sort of 'disposable cartridge'. There are plenty of ELISA based throw away, non powered, no computer required tests available even over the counter. Pregnancy tests and drug screens are two really common ones.
What I don't see is why the researchers had to hook the thing up to a smartphone (or any other bit of electronics) in the first place. Perhaps there are some technical details that require, for example, UV florescence to get the signal up but this isn't clear. They use a custom (read more expensive) cartridge for the three tests. You aren't going to get those things in a convenience store in the Middle of Nowhere. Especially nowhere's that can't even afford disposable gloves.
Yeah, I'm being a bit snarky here but we've seen dozens of these things 'on a smartphone'. Touted for low resource areas because there are smartphones and little else but hampered by the fact that the smartphone really isn't doing all that much more than five dollars of cheap Chinese electronics could do and further they need some other expensive 'special sauce' to work. I would hope (vainly of course) that the 'journalists' could perhaps dive a few millimeters deeper than they do.
But who am I kidding?
Faster! Faster! Faster would be better!
More and more Craigslist purchases are occurring in police station lobbies to ensure the safety of both parties. This tech should be available as well for CL hookups (protected from tampering by either - any? - of the prospective partners, of course). I can't think a better way of striking a blow against STD transmission rates.
Of course, it will never happen as this puritanical country (US) still can't come to terms with adult, consensual, out of wedlock casual sex., so STD away, as it's God's Punishment (TM) for daring to enjoy the pleasure he 'created'.
so with the humans off the table what were you looking to reproduce with?
What's the false positive and false negative rates of this cheap test, vs the normal one? While it's probably better to have a mediocre test rather than none at all, there are times when that's not true... high false positive rates for rare conditions can waste resources on healthy individuals. High false negative rates for common conditions can give patients a false sense of safety.
The specificity of the test matters a lot before you can judge its utility.

The very next comment after mine starts with "Imagine if you can prick the finger of a hooker in a Pattaya bar while you're drinking". Tell me again that warning people not to share a device like that is unnecessary.
So rather than read, you decide to double-down on the stupid.
Let me explain this loudly and slower so you may understand.

Thrown away, into the trash. With the cap placed back on so nobody gets stuck. They come in boxes of 100 and they are fucking cheap. No sane person re-uses a lancet.
You're exhibiting some weapons-grade stupid there, guy.

1. Your friends are violent criminals/psychopaths. They will harm people regardless of this being available. Pick some better friends.

There are three kinds of falsehood: the first is a 'fib,' the second is a downright lie, and the third is statistics.
